Step-like spectral distribution of photoelectrons at the percolation threshold in heavily -doped GaAs
S. V. Poltavtsev, R. I. Dzhioev, V. L. Korenev +3
We study the origin of the step-like shoulder on the high energy side of the low temperature photoluminescence spectrum of heavily -doped GaAs. We show experimentally that it is…
Nuclear spin-lattice relaxation in p-type GaAs
M. Kotur, R. I. Dzhioev, M. Vladimirova +6
Spin-lattice relaxation of the nuclear spin system in p-type GaAs is studied using a three-stage experimental protocol including optical pumping and measuring the difference of the…
Optical orientation and alignment of excitons in ensembles of inorganic perovskite nanocrystals
M. O. Nestoklon, S. V. Goupalov, R. I. Dzhioev +12
We demonstrate the optical orientation and alignment of excitons in a two-dimensional layer of CsPbI perovskite nanocrystals prepared by colloidal synthesis and measure the ani…
High-efficiency optical pumping of nuclear polarization in a GaAs quantum well
R. W. Mocek, V. L. Korenev, M. Bayer +6
The dynamic polarization of nuclear spins by photoexcited electrons is studied in a high quality GaAs/AlGaAs quantum well. We find a surprisingly high efficiency of the spin transf…
Nuclear spin relaxation in n-GaAs: from insulating to metallic regime
M. Vladimirova, S. Cronenberger, D. Scalbert +7
Nuclear spin relaxation is studied in n-GaAs thick layers and microcavity samples with different electron densities. We reveal that both in metallic samples where electrons are fre…
Nuclear spin warm-up in bulk n-GaAs
M. Kotur, R. I. Dzhioev, M. Vladimirova +3
We show that the spin-lattice relaxation in n-type insulating GaAs is dramatically accelerated at low magnetic fields. The origin of this effect, that cannot be explained in terms…
